To all whom t may concern.'

Be it known that I, LOUIS ROOVERS, engineer, of Brussels, in the Kingdomof Belgium, have invented new and useful Improvements in Valves,Stop-Cocks, and the Like, (for which no patent has been obtained in anycountry except in Belgium the 19th of December, 1885, No. 71,802; inGermany the Lith of February, 1886, No. 86,254, in France the 13th ofl\Iay,1886,No.176,115; in Austria the 31st of October, 1886, No. 19,829,and in England the 19th of June, 1886, No. 8,l59,) of which thefollowing is a specification.

My invention has for its object to provide a stop-cock or faucet whichwill be very efficient in checking the flow, and at the same time beeasy of operation; and it consists in certain features of noveltyhereinafter described with reference to the accompanying drawings, andparticularly pointed out in the claim.

1n the said drawings,Figure 1 is a vertical longitudinal section of afaucet embodying my invention, and Fig. 2 is a sectional plan of thesame.

The shell or casing` is represented at a, and the supplypipe at a. crepresents a hollow reciprocating plug, whose outer end is closed andprovided with an external flange f2,aud whose'side is provided with anumber of obliquely-arranged perforations d, which permit of the escape0f the uid from the said hollow plug. Held within the housing or neck b2of the casing a by means of a packnut c2 is a suitable packing-ring h,through which the plug c passes, and surrounding the outer end of theplug is a spiral spring f3, which bears against the flange f2 and theend of the housing or inner wall of the casing a. Thus it will be seenthat the said spring will have a normal tendency to draw the plug c outof the packing, thereby uncovering the perforations d and permitting theiiuid to escape through the hollow plug and its perforations into thecasing a, from whence it runs by the spout. As a means for forcing theplug c back into the housing with its perforations covered by thepacking-ring, I

provide a vertical stem or spindle g3,suitably stepped in the bottom ofthe casing, as shown in Fig. l, and journaled at its upper end in asuitable packing-box b', above which latter it is provided with anysuitable operating lever or handle, and secured to this stem is a cam f,which bears in a groove in the outer end of the plug c, as shown in Fig.1, and thus serves to support the said end of the plug when the latteris forced outward by the spring. The cam has the form shown in Fig. 2,and by which it will be seen that when the spindle or stem g3 is rotatedin one direction the plug will be reciprocated bythe conjoint action ofthe spring and cani, the latter serving to force it in, while the springserves to force it out. The cam should, however, be rotated in but onedirection, and therefore I restrict the rotation of the spindie by meansof a ratchet-disk g, secured to the spindlc,and a fixed pawl g,titted toslide vertically in a socket g2, which rests on the said ratchet inengagement with its teeth, and thus the stem is prevented from beingrotated in the wrong direction; and, also, the possibility of the actionof the spring upon the cam forcing the valve open accidentally isprecluded. Supposing, now, the point of the cam f to be bearing againstthe end of the plug and holding the perforations under the packing, itwill be seen that should the cam be further rotated in the direction ofthe arrow the plug would be suddenly released, whereupon the springwould instantly force it outward into the position shown in Fig. 2. Thisaction would cause a sudden opening, modified slightly by reason of theperforations d being arranged obliquely.

Having thus fully described my invention and in what manner the same isto be performed, what I claim is- In a stop-cock, the combination, withthe valve-housing, of a hollow plug open at one end and plugged at theother, iitted to rec-iprocate in said housing and having a number ofperforations CZ, a packing-ring surrounding said plug, a fiange on theouter end of said plug, a spring-bearing between said liange and housingand adapted to draw the perfoand tted to slide vertically in saidsooket, rated end of said plug out oir: said packing, substantially asset forth. a. vertical stem, a cam ou Said stem ttingli LOUIS ROOVERS.
